CAMERA UNIT, VEHICLE, AND METHOD FOR MANUFACTURING CAMERA UNIT
First Claim
1. A camera unit comprising a camera casing, a lens, and an image capturing element that is disposed in interior of the camera casing, wherein:
- a recess is formed in the camera casing on a side that is closer to a subject than the lens;
a portion or all of the recess is formed by a first wall portion, which is exposed on an exterior side of the camera casing and faces toward an optical axis;
the first wall portion extends in parallel with the optical axis or is inclined so as to separate away from the optical axis as is away from the lens toward the subject; and
a plurality of projections are arranged on the first wall portion alongside one another in a direction of the optical axis;
the plural projections comprising;
first surfaces, which are made up from flat or curved surfaces, sides of the first surfaces facing toward the lens being closer to the optical axis than sides of the first surfaces facing toward the subject;
second surfaces, which are made up from flat or curved surfaces, sides of the second surfaces facing toward the lens being farther from the optical axis than sides of the second surfaces facing toward the subject, or which are made up from flat surfaces that are parallel with the optical axis.

Abstract
Provided is a camera unit, a vehicle, and a method for manufacturing the camera unit. The first wall part of a housing for the camera unit extends parallel to an optical axis or in a slanted manner so as to gradually draw away from the optical axis in the direction from a lens toward a subject. A plurality of projections is disposed on the first wall part in alignment with the optical axis direction. The plurality of projections each have a first surface made up of a flat or curved surface in which the lens side is nearer to the optical axis than the subject side, and a second surface made up of a flat or curved surface in which the lens side is further away from the optical axis than the subject side, or made up of a flat surface parallel to the optical axis.

8. A method for producing a camera unit, the camera unit comprising a camera casing, a lens, and an image capturing element that is disposed in interior of the camera casing, wherein:
-
a recess is formed in the camera casing on a side that is closer to a subject than the lens; a portion or all of the recess is formed by a first wall portion, which is exposed on an exterior side of the camera casing and faces toward an optical axis; the first wall portion extends in parallel with the optical axis or is inclined so as to separate away from the optical axis as is away from the lens toward the subject; and a plurality of projections are arranged on the first wall portion alongside one another in a direction of the optical axis; the plural projections comprising; first surfaces, which are made up from flat or curved surfaces, sides of the first surfaces facing toward the lens being closer to the optical axis than sides of the first surfaces facing toward the subject; second surfaces, which are made up from flat or curved surfaces, sides of the second surfaces facing toward the lens being farther from the optical axis than sides of the second surfaces facing toward the subject, or which are made up from flat surfaces that are parallel with the optical axis, the method comprising the step of; setting angles of the first surfaces and the second surfaces to be equal to or greater than a draft angle.
